Well, one obvious way is to split it into ["a","b","c","d","e"] as 
google showed, select the bits you want, then join them back together 
again. Look at Array#join.

    ["a","b"].join("_")  # => "a_b"

Another way is to use a regular expression to match the patterns you're 
looking for. e.g.

    if string =~ /\A([^_]*_[^_]*)_(.*)\z/
      str1, str2 = $1, $2
    else
      raise "Unexpected format"
    end

There are many resources on ruby regular expressions you can google for.
